Skydeck Ledge The Skydeck Ledge at the Willis Tower is one of the city’s newest and most unique sightseeing attractions. There are four ledges which extend outward four feet from the building hovering 1,353 feet over street level. The ledges are constructed out of a heavy-duty transparent plexiglass allowing you to step out from inside the Skydeck producing a feeling like you’re walking on air. For those afraid to take the leap, you can still enjoy the already awesome panoramic view of the city.
